AngularJS行的总和NG-重复 [英] AngularJS sum of rows ng-repeat

问题描述

我动态添加行我表NG-重复，从一个数组的到来。

现在我想获得每行的所有款项（group.sum * group.perc / 100.0）的总和。我需要在一个变量，因为我需要进一步计算该值。谢谢

HTML

 ＆LT; TR NG重复=组中groupsArr＆GT;
  ＆LT; TD类=总-行NG模型=税＆GT; {{group.sum * group.perc / 100.0 |货币：}}＆LT; / TD＆GT;
＆LT; / TR＆GT;
 

SCRIPT

  VAR taxTotals = 0;
VAR taxTotals =
  对于（i = 0; I＆LT; group.length;我++）{
    将TaxTotal =将TaxTotal +组[I] .taxes;
};
的console.log（taxTotals）;
};
 

解决方案

创建过滤器：

  app.filter（'sumFilter'，函数（）{
     返回功能（组）{
         变种taxTotals = 0;
         对于（i = 0; I＆LT; groups.length;我++）{
             将TaxTotal =将TaxTotal +组[I] .taxes;
          };
         返回taxTotals;
     };
 }）;
 

使用的过滤器$服务：

  app.controller（'myController的'，函数（$范围，$过滤器）{
      $ scope.groups = [];      变种taxTotals = $滤波器（'sumFilter'）（$ scope.groups）;
      的console.log（taxTotals）;
 }）;
 

使用它在你的HTML：

 ＆LT; TR NG重复=组中groupsArr＆GT;
    ＆LT; TD类=总-行NG模型=税＆GT; {{group.sum * group.perc / 100.0 |货币：}}＆LT; / TD＆GT;
＆LT; / TR＆GT;
 ＆所述; TR＆GT;
      ＆LT; B＆GT;税收总计：＆LT; / B＆GT; {{groupsArr | sumFilter |货币}}
 ＆LT; / TR＆GT;
 

I add dynamically rows in my table with ng-repeat, coming from an array.

Now I want to get the sum of all sums per row (group.sum * group.perc / 100.0). I need it in a variable because I need this value for further calculations. Thank you

HTML

<tr ng-repeat="group in groupsArr">                                         
  <td class="total-rows" ng-model="taxes">{{group.sum * group.perc / 100.0 | currency :""}}</td>
</tr>

SCRIPT

var taxTotals = 0;
var taxTotals = 
  for (i=0; i<group.length; i++) {
    taxTotal = taxTotal + group[i].taxes;    
};
console.log(taxTotals);
};  

解决方案

Create a Filter:

 app.filter('sumFilter', function() {
     return function(groups) {
         var taxTotals = 0;
         for (i=0; i<groups.length; i++) {
             taxTotal = taxTotal + groups[i].taxes;    
          };
         return taxTotals;
     };
 });

Use the $filter service:

 app.controller('myController', function($scope, $filter) {
      $scope.groups = [...];

      var taxTotals = $filter('sumFilter')($scope.groups);
      console.log(taxTotals);
 });

Use it in your HTML:

<tr ng-repeat="group in groupsArr">                                         
    <td class="total-rows" ng-model="taxes">{{group.sum * group.perc / 100.0 | currency :""}}    </td>
</tr>
 <tr>
      <b> Tax Totals: </b> {{ groupsArr | sumFilter | currency }}
 </tr>
